Squatting is the natural way to poop. Humans have always squatted - there were no toilets in the pre-historic age and it is only in fairly recent times that we have had porcelain toilets to sit on. Many people who suffer from constipation find squatting works much better. I had a friend who lived in Dubai (where their toilets require you to squat) and she said she never suffered constipation while she was there. A baby poops lying down because they cant squat. as soon as they walk they squat. Humans are meant to squat.
